Abstract
The utility model discloses a double-layer condenser for a dewar flask, which comprises an outer cylinder, a heat preservation layer, an inner cylinder, a copper tube, a distributing head, a liquid level meter, a pressure gage, a primary safety valve, a secondary safety valve, a gasification gas phase valve, a liquid phase valve, a gas phase valve, a gas outlet valve and the like. The heat preservation layer is arranged between the outer cylinder and the inner cylinder, the copper tube is wound at the bottom of the inner cylinder, one end of the copper tube is connected onto an analysis instrument through the gas phase valve, and the other end of the copper tube is connected onto a client-side through the gas outlet valve. The double-layer condenser for the dewar flask is capable of satisfying requirements of different clients, low in storage pressure, good in safety performance, free of danger of high-pressure explosion, recycled, environment-friendly and energy-saving.
Description
Technical field
The utility model relates to the vacuum heat-insulating container of a kind of shipment, storage liquid gas, is storage liquid gas, a kind of more satisfactory container and the instrument of low temperature research and crystal element protection.
Background technique
Dewar vessel has been widely used in scientific research because thermal insulation property is good, and health care is in the relevant field such as oil drilling.Some special industries need be used the liquid gas of ultralow temperature, need like electron trade, food service industry fresh-keeping, but the Dewar vessel now on the market can not well be preserved ultralow temperature gas, does not reach the ultralow temperature gas that some special industries need.Liquid gas originally is connected on the analytical instrument through air compressor, and the gas of so original low temperature has just become gas at normal temperature input user side.But some special industries need the gas (like oxygen, nitrogen etc.) of ultralow temperature, just do not meet client's needs, have designed the double-deck Dewar vessel condenser of the utility model in order better to solve client's demand.
The model utility content
The purpose of this patent is to provide a kind of uniqueness double-deck design of condenser, satisfies different customer demands, storage pressure is low, Security good, no high pressure explosion risk, recycles the double-deck Dewar vessel condenser of environmental protection and energy saving.
A kind of double-deck Dewar vessel condenser comprises urceolus, thermal insulation layer, inner core; Copper pipe, distributing head, level meter, pressure gauge; Primary safety valve for inner container, secondary safety valve, gasification gas valve, liquid phase valve; Gas valve, gas outlet valve etc., said copper pipe are coiled in
copper pipe that is lower than whole inner core and select to twine the number of turns according to the height of client's needs temperature; Just twine a little copper pipes when needing low temperature more, need temperature higher, just twine less.One of copper pipe is connected on the analytical instrument through gas valve, and the other end is connected client end through gas outlet valve.It between the inner/outer tube thermal insulation layer of a vacuum; Copper pipe is inserted interior tube bottom; Pour into the liquid body (consistent) of ultralow temperature through the outlet pipe at liquid phase valve place, utilize these liquid low temperature to cool off the gas of the normal temperature in the inner core, reach the effect of a cooling with the gas in the copper pipe; After the temperature of the liquid body of ultralow temperature that the GAS ABSORPTION in the copper pipe pours into, reach the temperature output of a satisfaction.The higher temperature of gas in liquid bulk absorption copper pipe; Reach a gasification; Make in the inner core because gasification produces certain pressure; Outlet pipe through primary safety valve for inner container, gentleization of secondary safety valve gas valve place is discharged the gas that becomes normal temperature, directly receives and analyzes can on the analytical instrument, circulates.
As preferably, the central position respectively is provided with a level meter and pressure gauge on the said distributing head, leads to inner core through outlet pipe respectively, and said level meter leads to interior tube bottom.Level meter is used for measuring the volume of liquid body in the inner core, and pressure gauge is used for monitoring at any time the pressure of inner core gasifying gas, causes bottle impaired to prevent overpressure.
As preferably, a side is provided with that an outlet pipe leads to inner core and through primary safety valve for inner container, gentleization of secondary safety valve gas valve is connected with analytical instrument on the said distributing head.
As preferably, on the said distributing head opposite side be provided with an outlet pipe lead in tube bottom and be connected with liquid phase valve.
As preferably, said primary safety valve for inner container is set to 1.6mpa, and secondary safety valve is set to 2.0mpa, and when the pressure limiting index that arrives separately, safety valve is opened automatically, and unnecessary pressure in the drain tank guarantees that safety prevents overpressure and impaired.
